Chapter 1 Chemical Foundations 1.8 Density
Chapter 1 Chemical Foundations Density Copyright 2005 by Pearson Education, Inc. Publishing as Benjamin Cummings 1. Density Density Compares the mass of an object to its volume. Is the mass of a substance divided by its volume. Density expression Density = mass = g or g = g/cm3. volume mL cm3. Note: 1 mL = 1 cm3. 2. Densities of Common Substances 3. Learning Check Osmium is a very dense metal. What is its Density in g/cm3 if g of osmium has a volume of cm3? 1) g/cm3. 2) g/cm3. 3) 111 g/cm3. 4. Solution Given: mass = g volume = cm3. Plan: Place the mass and volume of the osmium metal in the Density expression. D = mass = g volume cm3. calculator = g/cm3. final answer (2) = g/cm3. 5. Volume by Displacement A solid completely submerged in water displaces its own volume of water.
